A novel surface-enhanced Raman scattering (SERS)-active surface prepared by attaching silver nanoparticles in the multiwalled carbon nanotube (MWCNT)-Nafion is described. The resulting Ag-MWCNT-Nafion nanocomposite was characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy. The application of the Ag-MWCNT-Nafion nanocomposite in SERS is investigated by using rhodamine 6G (R6G). The SERS intensities of R6G at the Ag-MWCNT-Nafion-coated indium-tin oxide (ITO) substrate are greater than those at the Ag-coated and Ag-carbon black-Nafion-coated ITO substrates. The in situ determination of R6G in aqueous Solution with SERS method at the Ag-MWCNT-Nafion nanocomposite displayed a line range from 10(-8) to 10(-5) M. The present methodology demonstrates that the nanocomposite film composed of Ag, MWCNT, and Nafion is potential for optical chemical sensor applications. (C) 2009 Elsevier B.V. All rights reserved.
